Field Asset Services (Part 1): Utility Work is a Top Dangerous Job
Industry professionals understand the risks line workers face all too well. However, many customers may be surprised to learn that installers and repairers are among the top ten most dangerous jobs in the country. This statistic includes fatal work injury rates, according to the Bureau of Labor Statistics. Many others suffer non-fatal injuries from electrical burns and mechanical trauma.
The leading cause of injury is worker contact with overhead power lines. The amount of voltage carried along electricity wires can range from a few thousand volts to over 100,000 or more. At the same time, the average age of utility poles in the United States is nearing projected life expectancy. Between the physical structure and electrical capacity, utility poles and other parts of the plant have the potential to cause a lot of damage.
Utility workers’ jobs are essential to the daily function of our country’s network asset infrastructure – they ensure that power and communication flows to hospitals, schools, businesses, homes, streetlights, retail stores, and airports. Without them, everything goes dark. It is crucial that safety measures continue to evolve to reduce the risk for these important and necessary jobs.
Unknown Field Conditions Creates Unnecessary Risk
measures dictated by the National Electric Safety Code, OSHA and individual utilities and communications companies, as well as extensive training and certifications.
While safety measures address commonly expected situations, often the unexpected is most dangerous. The U.S. continues to face aging power and communications infrastructure. It is common for technicians to locate equipment failures on the job, and previously unknown field conditions of assets due to aging equipment, poor communications, and out-of-date records. This puts field workers at even greater risk.
For example, a line worker may be unaware that a utility pole has internal damage due to any number of stressors, such as:
- Attachment weight
- Moisture content
- Wood decay or rot
- Hollow areas and cracks
- Insect damage
- Severe weather
- Vehicular accidents
Among all these stressors, attachment weight and pole overloading are fast-growing threats. Demands on field assets continue to increase as communications build-outs expand further, creating changes more quickly than asset owners can track. Often there are situations in which a utility pole is leaning or otherwise damaged and needs to be replaced, but the pole owner doesn't have visibility into those safety risks.
For assets owners and attachers whose equipment is spread over massive geographic areas – hundreds or thousands of miles – the challenges of maintaining and managing a huge quantity of assets is a struggle. Companies may not have sufficient awareness or access to current conditions at any one time, and those conditions are constantly changing as assets are affected by:
- Newly attached equipment
- Storms, fires, and insects
- Events such as a car hitting a pole
- Maintenance or repair activities that may not be up to code
It is difficult to feel in control without access to critical, time-sensitive data. This lack of empowerment has created infighting and conflict between asset owners and attachers. Simply put, it’s better when all industries involved in joint use work together.
If field workers cannot be appropriately prepared for the current conditions – due either to a lack of available data or incorrect data – their health and safety are unnecessarily at risk. To protect employees and the public from injury, regular asset inspections are necessary. In many cases, risk can be greatly reduced simply by removing double poles, also known as double wood or "buddy poles." In our next article, we will discuss strategies for improving regular asset inspections and the associated data management.
